4 Claims. (cite-41st This invention relates to refrigeratorconstructions and-more particularly to constructions especially adaptedforhousehold or domestic refrigerators. I

An object of this invention is a constructionemploying amotor-compressor-tan unit, and an air cooled condenser, all enclosedwithin aibuiIet top casing or cover provided with a suitable air inletand an outlet. In the preferred embodi-' M ment of the invention thecondenser forms ashield or screen for the motor-compressor-fan unit, andan auxiliary or second casing forms an enclosure for themotor-compressor-tan unit per se, the condenser being exposed withinthe.

1B prime casing.

Still further objects will readily occur to those skilled in the artupon reference to the following description and the accompanyingdrawings in which 39 "Fig. 1 is a top view, as it in sectionon line 1--1of Fig. 2.

Fig. 2 is a rear view, as if in section on line 22 0f Fig. 1; I Fig. 3is a sideview, as it in section on line '25 3-3 or Fig. 1.

Referring to the drawings, it will be seen that the constructionincludes .a cabinet having a top wall 12 and a mounting board 14, therebe-' ing a bufiet top or casing 16 forming a cover.

Supported on and secured to the mounting board is a motor-compressor-fanunit including a motor 20, a compressor 22, and a fan 24, all having thecommon shaft 26. A condenser 28, comprising a vertical row orend-connected pipes, is also supported on the board 14, its plane andsubstantially perpendicular to the top wall of the cabinet. Thecondenser partitions the casing 16 into an operating compartment and 0an air compartment, as can be seen readily.

Disposed within the casing 16 is a second casing or enclosure having :atop wall 36, endwalls 38 and 39, and a side wall 40. One oil the end'walls 38, is apertured, as at 42, and the blades of the fan are disposedwithin the aperture, so as.

to form thereof, an outlet port thru which the Ian may discharge. l'heenclosure or second casing, further, is so disposed within the casing 16that the free edge of its top wall is adjacent being substantiallyparallelto the fan shaft 26 other of which, 52, forms the air outlet.The inlet extends down to near the base 0! the cabinet, and its upperend is closed. and is disposed immediately above the air inlet opening54 of the casing 16. The outlet 52 also extends downwardly, tho not sofar as does the inlet 50, and its upper end is closed at 56, and isdisposed immediately. above an. opening 58 in the casing 16, this lastopening being aligned with the opening 42 of the enclosure.

When the fan is operating, cool air is drawn upthru the inlet 50, andopening 54 into the casing 16. It is then drawn thru the condenser,extracting heat therefrom, and passes into the enclosure, being forcedout of the latter by the fan 24 which dischargesthru openings 42 and 58.and outlet tube 52.

Now having described the invention and the preferred embodiment thereof.it is to be understood that the said inventionis to be limited. not tothe specific details herein set forth, but

only by the scope of the claims which follow.

What I claim is: 1. In combination with a refrigerator cabinet having. amotor-compressor-ian unit on the top .wall thereof, a condenser also onthe top wall of the cabinet and comprising pipes in a vertical row whoseplane is substantially parallel to the axis of the fan and substantiallyperpendicular to the wall, a casing surrounding and covering the unitand the condenser and having an air inlet on its rear wall and on thatside of the condenser remote from the unit, and having an air outlet onits rear wall near the discharge path of the fan, a relatively longconduit for-- leading air to said inlet and a relatively shortconduitfor leading air from said outlet.

2. In combination with a refrigerator cabinet having amotor-compressor-fan unit on the top wall thereoi, a condenser, also onthe top wall of the'cabinet and comprising pipes in a vertical row whoseplane is substantially parallel to the axis of the fan and substantiallyperpendicular to the wall, a .casingsurrounding and vcovering the unitand'the condenser and having an air inlet on its rear wall and on thatside of the condenser remote from the unit, and having an air outlet onits rear wall near the discharge path of the fan, said condenser servingas a barrier between the air inlet and the tan and as a shield for thelatter, a relatively long conduit for leading air to said inlet and arelatively short conduit for leading air trom" said outlet.

3. In combination with a refrigerator cabinet having amotor-compressor-fan unit on the top wall thereof, a condenser also onthe top wall of the cabinet and comprising pipes in a vertical rowlwhoseplane is substantially parallel to the axis of the fan and substantiallyperpendicular to the wall, a casing surroundingand covering the unit andthe condenser and having an air inlet on its rear wall and on thatside'of the condenser remote from the unit, and having an air outlet onits rear wall near the discharge path of the fan, the air inletcomprising a tube on the rear wall of the cabinet and whose lower end isnear the base of the cabinet.

4. In combination with a refrigerator cabinet having amotor-compressor-fan unit on the top whose lower end is near the base ofthe cabinet,

the air outlet comprising a tube on the rear wall of the cabinet.
